Answer:
2/7
Step-by-step explanation:
Each time you play, you get 1 number. Since 8/28 numbers win, you have a 8/28 chance to win if you buy one ticket. 8/28 = 2/7
Use the rule of 3, note that we will convert the hours to minutes:
60 - 84
75 - x
(75 * 84) / 60 = x
6,300 / 60 = x
105 = x
105 minutes = 1h 45m
Hope it helped,
Happy homework/ study/ exam!
Answer:
1
Step-by-step explanation:
The rules for significant figures are:
- Non-zero digits are always significant.
- Zeros between significant digits are also significant.
- Trailing zeros are significant only after a decimal point.
In 13822, all of the digits are non-zero. So the first significant figure is 1.
Answer:
- -7.5x -12.5, x < -1
- 7.5x +2.5, x ≥ -1
Step-by-step explanation:
The absolute value function changes slope at its vertex. Here, that vertex is translated to x = -1. To the left of that point, the function is equivalent to one that negates its argument:
|x| = -x . . . for x < 0
|x| = x . . . for x ≥ 0
<u>for (x+1) < 0</u>
y = -7.5(x +1) -5 = -7.5x -12.5
<u>for (x+1) ≥ 0</u>
y = 7.5(x +1) -5 = 7.5x +2.5
This means we can write the piecewise function as ...
